Hi, I'm a junior developer, and this is my first time contributing to open source. I'm very interested in this issue and would love to give it a try. Since I'm new, I’d appreciate any guidance along the way. May I take this on?

Thank you for giving me this opportunity. As this is my first contribution, I’m planning to start by checking the Rust CI section in .github/workflows/ci.yml. Does this sound like the right place to start? I’d also appreciate any advice or documentation you think would be helpful for me.
